Detailed Product Description

The MPA Electrical WH513239 wheel bearing and hub assembly is designed to replace worn or damaged hubs on select Subaru vehicles. Its 27 spline count ensures compatibility with the drivetrain components, while the trapezoid flange shape with 4 bolt holes provides a secure mounting surface. The flange diameter of 5.446 inches and offset of 1.828 inches are engineered to match factory specifications, maintaining proper wheel alignment and vehicle handling.

This assembly supports an encoder-type ABS system, which is common in Subaru models, allowing the vehicle's anti-lock braking system to function correctly. Although the ABS sensor is not included, the hub is compatible with the existing sensor setup. The included gasket or seal helps prevent contamination and maintains bearing integrity. The 5 M12 x 1.5 wheel studs provide a secure fit for wheel installation, and the steel construction offers durability under normal driving conditions.

Common Applications and Problem Resolution

• Replacement for noisy or worn wheel bearings causing vibration or humming sounds
• Fixes wheel hub looseness or play affecting steering stability
• Restores proper ABS sensor encoder function to prevent warning lights
• Addresses wheel stud damage or corrosion impacting wheel security
• Resolves seal failure leading to grease leakage and premature bearing wear

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning installation. Remove the old hub assembly carefully, noting the orientation of the flange and ABS encoder interface. Clean the mounting surface thoroughly to ensure proper gasket sealing. Torque flange bolts and wheel studs to manufacturer specifications to maintain safety and performance. Verify ABS sensor alignment and operation after installation.
